FIELD

The disclosure relates to the field of LED illumination and more particularly to techniques for making and using active accessories for LED lamps.

BACKGROUND

Accessories for standard halogen lamps such as MR16 lamps include, for example, diffusers, color filters, polarizers, linear dispersion, and baffles. Such accessories are commercially available from companies such as Abrisa, Rosco, and Lee Filters. These accessories can be used to control the quality of light including elimination of glare, to change the color temperature of the lamp, or to tailor a beam profile for a particular application.

Generally, accessories for halogen lamps are required to withstand high temperature and may be made of glass, and often require special mechanical holders or fixtures to incorporate with the halogen lamp. Often, such halogen lamp accessories require disassembly of the lamp from the fixture to incorporate the accessory into the fixture. This set of disadvantages results in the accessories having high costs and being cumbersome to install.

At the same time, miniaturized electronics have become very small and relatively inexpensive, thus providing an opportunity to deploy miniaturized electronics adapted as active accessories in conjunction with LED lamps.

Therefore, there is a need for improved approaches for configuring selections of one or more active and/or passive accessories to mate with LED lamps.

SUMMARY

This disclosure relates to apparatus allowing for simple and low cost implementation of accessories for LED lamps that can be used to retrofit existing fixtures. In other words, the accessories disclosed herein are compatible with fixtures that may not have been designed to be used with such accessories. In certain embodiments, disassembly of LED lamps is not necessary for installation of the accessories.

Many of the embodiments herein address use of an active electronic component that is integrated into or used with an LED lamp. Some implement electronic circuitry in a base, and some implement electronic circuitry (including connectivity) in a “smart” adapter. Examples of such embodiments are included in the appended figures and in the description.

DETAILED DESCRIPTION

The term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete fashion.

The term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or is clear from the context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A, X employs B, or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or is clear from the context to be directed to a singular form.

“Accessory” or “accessories” includes any mechanical or electro-mechanical component or electrical component or fixture to be mated to a lamp. In certain embodiments, an accessory comprises a thin, optically transparent film, sheet, or plate.

Reference is now made in detail to certain embodiments. The disclosed embodiments are not intended to be limiting of the claims.

FIG. 1 shows a housing 100 for implementing active accessories in an LED lamp. The LED lamp includes a heat sink 102 and a base 104 and light (arrows) emanating from the optic.

In some embodiments, the housing has an inner volume (center cross-hatched area) suited for situating electronic components such as power conditioning circuitry and/or microprocessors and sensors.

FIG. 2 shows an adapter 200 used to provide active accessories in an LED lamp. The LED lamp includes a heat sink, lens, magnet 2023, magnet 2024, an accessory, and electrical contacts N 200 (contact N, contact 1 and contact 2).

A plurality of contacts can be positioned atop the lens, and the contacts can be configured to provide an electrical connection to electronic components such as power conditioning circuitry and/or microprocessors and sensors. In some embodiments, an adapter uses magnetic forces to hold an accessory in place.

FIG. 3 shows superimposed profile shapes 300 found in a range of lamp standards adapted to be used for providing active accessories in an LED lamp. FIG. 3 also shows smart light electronics 302 electrically connected to an adapter within expansion slot 304.

A home or business may have several lamp types installed. Creating a set of smart accessories that fit any/all of these lamp types, and communicate with each other and with a central computer, in a consistent manner enables the consumer or business owner to monitor and control their environment efficiently and effectively. The accessories can have unique identifications and communicate with each other and a central computer using standard protocols such as uPnP, DLNA, or other interoperable or interoperability protocols. By using an expandable approach (e.g., using smart buttons versus a pre-integrated one that has the smarts built into each lamp) allows the lamps to be integrated into any operational environment of building management systems or smart lighting systems using a choice of smart buttons, and without having to replace the lamps.

FIG. 4 show san exploded view of an assembly 400 found in a range of lamp standards adapted to be used for providing active accessories in an LED lamp. The LED lamp includes a base 440, a plug 450, a heat sink 430, a circuit including the LED 420, retaining ring 410, optic 460, and retaining ring 470.

FIG. 5 shows a top view of a hybrid connector 500 adapted to be used for providing active accessories in an LED lamp. The adaptor includes electrical contacts 504, a keyed connector 502, and a magnetic centroid 506.

A standard interface like USB can be implemented using a simple connector with 4 or 5 terminals that carry power and data. USB provides the opportunity to leverage the vast ecosystem of systems and devices that have been built for the past few decades for PCs, CE devices, smartphones, etc., as well as the continuous evolution of the interface to accommodate new usages for consumers and businesses.

FIG. 6 shows a side view of a hybrid connector 600 adapted to be used as a USB slave device for providing active accessories in an LED lamp.

A lamp can be built with a standard microcontroller or microprocessor with associated software, and with or without persistent connectivity to other devices or a central computer. The microcontroller or microprocessor can be used for internal lamp functions like controlling the LED driver, storing operational data like hours of usage, current and temperature data, etc. By attaching a smart USB Slave button, the functionality of the lamp can be extended to include wireless communication to other lamps and a central computer for lamp monitoring and control, connection to peripheral devices like a camera and sensors.

FIG. 7 shows a side view of a hybrid connector 700 adapted to be used as a USB master device for providing active accessories in an LED lamp.

A lamp can be built with even without a microcontroller or microprocessor, yet supporting a simple USB-based readable storage that stores operational data of the lamp like hours of usage, current and temperature data, etc. Once a smart USB Master button that has a microcontroller or microprocessor is connected to the lamp, that USB device can be read by the microcontroller or microprocessor on the smart button. The smart button can also integrate wireless networking to implement lamp monitoring and control, and can communicate with other lamps and/or can communicate with a central computer. It may also contain a camera and/or other sensors.

FIG. 8 shows a side view of a hybrid connector 800 adapted to be used as power-delivery device for providing active accessories in an LED lamp.

A lamp can be built with a device that provides power to the smart button connector. When a smart USB Master button that has a microcontroller or microprocessor is connected to the lamp, the lamp can be turned into a smart lamp. The smart button can integrate wireless networking to implement lamp monitoring and control, and communication with other lamps and a central computer. It may also contain a camera and sensors. It may also contain readable storage that stores operational data of the lamp such as hours of usage, current and temperature data, etc.

FIG. 9 shows an exploded view of an assembly 900 found in a range of lamp standards adapted to be used for providing active accessories in an LED lamp. The LED lamp includes a magnet 9023, having a treated surface 902, a lens, and an emanated light pattern 904.

One embodiment disposes accessories on the face of the lamp, in a proximity that is thermally isolated from the heat source and high temperatures of the LED. In certain embodiments, the face of the lamp is open to the environment so as to facilitate heat dissipation of any electronics. Such a face-mounting further facilitates antenna placement (e.g., for wireless operation), and for camera and sensor operation. It also makes it easy to connect and disconnect accessories.

In certain embodiments, an LED lamp comprises a lens having a center and a diameter; a first magnet attached to the center of the lens; a first accessory disposed on the lens; and a second magnet attached to the center of the first accessory; wherein the first magnet and the second magnet are configured to retain the first accessory against the lens.

FIG. 10A depicts an LED lamp with an accessory as an exemplary system having improved accessories for LED lamps.

FIG. 10B shows an exploded view of an LED lamp with an accessory in a system having improved accessories for LED lamps.

FIGS. 10A and 10B show an example of an LED lamp having an MR16 form factor including a heat sink. A lens is attached to the heat sink or other part of the lamp. In certain embodiments, the lens comprises a folded total internal reflection lens. Attachment may be mechanically such as using prongs as shown in FIGS. 10A and 10B. A magnet is attached to the center of the lens. An accessory having a magnet attached to the center can be disposed over the lens and the opposing magnets can hold the accessory to the lens. The first and second opposing magnets can be configured to retain the accessory against the perimeter of the lens. For example, the opposing magnets may have the opposite polarity. The accessory may have substantially the same diameter as the lens, and in certain embodiments covers an optical region of the lens, such as for example greater than 90% of the optical aperture of the LED lamp. In certain embodiments, the accessory comprises a transparent film such as for example a plastic film. In certain embodiments, the accessory is selected from a diffuser, a color filter, a polarizer, a linear dispersion element, a baffle, and a combination of any of the foregoing. In certain embodiments, the first magnet and the first accessory have a combined thickness less than about 3 mm, less than about 2 mm, less than about 1 mm, less than about 0.5 mm, and in certain embodiments, less than about 0.25 mm.

FIG. 11 shows an exploded view 1100 of an LED lamp with multiple accessories in a system having improved accessories for LED lamps.

In certain embodiments as shown in FIG. 11 , an LED lamp comprises a second accessory disposed adjacent a first accessory. In certain embodiments, a second magnet is attached to the center of the second accessory and is used to affix the second accessory to the lamp. In certain embodiments wherein the lamp comprises a second accessory, a magnet is not attached to the center of the first accessory.

There are many configurations of LED lamps beyond the depicted MR-16 lamp. For example, Table 1 gives standards (see “Designation”) and corresponding characteristics.

Additionally, a lens may comprise a bulb or remote member used in forming the LED lamp. The aspect of a center can mean a center from the perspective of any center, or even a centroid (from any view) as in the case of an irregularly shaped lens.

Accessories and methods of attached accessories disclosed herein may be used with any suitable LED lamp configuration including without limitation any of those disclosed in Table 1 and/or in combination with any form factors disclosed in Table 2.

FIG. 12 depicts an environment 1200 within which LED lamps with multiple active accessories can be deployed. In particular, FIG. 12 depicts an arrangement of various lights (e.g., lamps and or fixtures) positioned in a way as to provide useful illumination both for general illumination lamps (e.g., down lamps) as well as lamps for task lighting at working surfaces 1205. There may be incidental sources of light (e.g., ambient light 1202), for example, natural light or other illumination entering the environment through a window or door.

The various lights may be grouped together in a way that is commonly known as a zone. In a lighting zone, the lamps within a group act together in their potentially variable light output. One or more of the lights may have active electronic accessories attached (“SNAPs”) which provide one or more various functionalities. In some situations, one or more or all of the lamps may be in communication with one or more of other lamps, and/or in communication with a controlling and/or monitoring device and/or the Internet (e.g., via a cloud-based control/monitor). One or more or all of the lamps may also have sensors to assess ambient light, motion, occupancy, temperature, IR data, proximity, gasses (e.g., CO, CO₂, methane, etc.), products of combustion (e.g., from fire or smoldering), smoke (e.g., cigarette smoke, compound-laden vapors, etc.), humidity, human body temperature, remote object temperature (e.g., by IR sensing) etc.

Any number of these sensors may be constructed into a SNAP form factor, and any number can be attached in any combination to one or more lamps. There may be one or more sensors (with or without wireless communication functionality) on a SNAP accessory, and there may be one or more SNAPs attached to a single lamp.

In one embodiment, a particular lamp (perhaps near a door) has a motion sensor SNAP attached. Another lamp (perhaps near a window) has an ambient light sensor. Certain lamps and/or attached SNAP accessories may have a wireless or IR communication function, and individual ones or groups of lamps can be individually or in groups as pertaining to one or more zones. Zone marking SNAPs are further discussed infra. Zone marking SNAPs may or may not be permanently affixed. In some cases a remembered zone designation may be “imparted” from an accessory to a lamp and henceforth remembered by the lamp. The impartation can occur merely through momentarily attaching a zone marking SNAP to the lamp. In such scenarios, similarly-zoned lamp can operate and/or cooperate in a group. For example, a light having a motion sensor can cause all lamps sharing the same zone designation to become activated when motion is detected. Concurrently, perhaps in the same zone or part of the zone, or in a different zone, a communication unit and/or ambient light sensor will cause certain lamps near a window to dim when incoming ambient light is sensed.

Manual control over each lamp or group of lamps can be managed under wireless control and/or under IR control, with or without intervention by an occupant of the room, or with or without intervention by an automated controller, or with or without intervention or by a remote controller located remotely from the subject lamp or group of lamps. The SNAP accessories may be freely re-deployed (e.g., to a different lamp or to a different location) and the re-deployment enables new functions corresponding to the new arrangement.

Programmed functionality may be offered by the combination of an automated controller and additional SNAPs or by the SNAPs themselves. A “Fire Egress” SNAP could designate a lamp to be always on even if dimmed 24 hours a day. An event trigger such as a detected open flame, smoke or an external signal of a fire alarm (e.g., perhaps coming through the programmed controller) being tripped can cause the lights to come to a preset maximum intensity, and/or with egress indications (e.g., illuminated arrows and/or blinking to attract attention).

Some combinations include various forms of an “Enterprise Outlook” SNAP so that an email address can become the address of a lighting system (e.g., group of lamps, similarly-zoned lamps, etc.) can become the address of a specific lamp. Strictly as one example, sending an email to lamp-on.name@domain.com might control the task light at Name's desk.

Further active elements and sample functions are given in the following tables.
